Count buffers dirtied due to hints in pgBufferUsage.shared_blks_dirtied.
Previously, such buffers weren't counted, with the possible result that
EXPLAIN (BUFFERS) and pg_stat_statements would understate the true
number of blocks dirtied by an SQL statement.
Back-patch to 9.2, where this counter was introduced.
